The main procedures employed so far to deal with phisical and geometrical descontinuities in Boundary Element analysis are studied. Two approaches are studied to form the complete global matrix combining the FEM and BEM: one obtainning an equivalent matrix from the Boundary Element matrices and another by the condensation of the Finite Element Matrix on the boundary nodes.
